Application led June 19, 1922. Serial No. 569,450.

T o all whom t may concern:

Be it known that I, EvinY L. lVIsHoN, a citizen of the United States,residin at Picher, in the county of Ottawa and tate of Oklahoma, haveinvented certain new and useful Improvements in Pullin and LiftingDevices, of which the fol owing is a specification.

This invention relates to lifting and pulling devices, and the rimaryobject of the invention is to provi e a combined instrument which can beeffectively used as a vehicle jack for raising vehicles or other loadsto various heights and as a pulling device for stretching wire or forpulling automobiles out of mud and the like.

Another object of the invention is to provide a novel tool embodying asupporting frame having associated therewith a sliding lifting standard.a rotatable drum, means for rotatingr the drum, and chains adapted topass around the drum for detachable connection with either the liftingstandard or with a device to be pulled.

A further object of the invention is to provide a novel means foranchoring the base or frame in position against movement when theimproved pulling and lifting device is used for stretching wire or forpulling automobiles out of the mud.

A further object of the invention is to provide a novel means forconstructing the lifting standard whereby the same will form a guide andguard for the chain, which is adapted to pass about the drum. when thechain is used for pulling vehicles out of the mud or the like.

A further object of the invention is to provide a novel and simple meansfor actuating the drum so that the said lifting standard can be easilyactuated with a minimum amount of efort.V

A further object of the invention is to rovide a novel drum for thechains, where- Ey the necessity of the chains being wound about the drumis dispensed with, thereby eliminating the use of the large andcumbersome drum for the chains to wind about.

, A still further object of the invention is to provide a combinedjackand puiling. delviceof the abovecharacter, which will be durable andefficient iii use, one that will be simple and easy to. manufacture, andone .which can be; placed upon the market at a reasonable QSS.

With these and other objects in view, the invention consists in thenovelconstruction, arrangement and formation of parts, as Will be hereinaftermore fully described` claimed and illustrated in the accompanyingdrawings, forming a part of this specification, in which drawings: Y n

Figure 8 is a longitudinal section through the improved device, showingthe same 1n use. as a pulling Referring to the drawings in detail,wherein similar reference characters designate corresponding parts`throughout the several views. the letter A indicates the frame of theimproved device; B, the novel actuating drum; C, the means for operatingthe drum; D, the meansrfor preventing retrograde movement of the drum;Ez the lifting standard slidably mounted wlthin the frame; F, and F the`lifting and pulling chains; and G, asupport to which the device can beattached when the same is being used as a pullng or stretchinginstrument.

The frame A includes a base plate 10 to which is secured upstandingvertical side bars 11 and 12. The side bars or standards; 11 and 12 havetheir inner faces channeled to provide guideways 13n forA the recepgonYof the lifting standards E which will here- .inafter` more fullyYYdescribed. y Suitable braces or strips 174 areputilized for connectingthe side pleces or standardsllI c1112 together as Aclearlyshown inFigures 1, 2, and 3 0f. the drawings. i

The frame A supports the B around ion which is adapted to pass thepulling or lifting chains F, and F and this drum includes thecylindrical body or liubfl and the side ang 16, which are of a discshape. These disc shaped flanges 16 have their peripheries provided withteeth to provide ratchet Wheels 17. The periphery of the drum is cast orotherwise formed to conform to the configuration of the links of thechains F and F', so that the said drums will constitute a combined lockand pull for the chains, eliminating the necessity of rigidly securingthe chains to the drum and the Winding of the chains about the drum. Theperiphery of the drum is provided with substantially oval shapeddepressions 16 to receive the lia-t links of the chains and connectinggrooves for receiving the upright cross links of the chains. This drumis rotatably mounted upon a supporting sha-ft 18.I which is supported bythe side standards or pieces 11 and 12. If desired, these standards orpieces 11 and 12 may be provided With suitP able bearings for receivingthe said shaft. It is preferred that the terminals of the shaft 18extend bevond the side standards or pieces 11 and 12 in order to form afnlerum or Yrocking support for the actuating members C which will nowbe described The actuating member C includes a hand lever 20, theforward or inner end of which is bifurcated to provide a yoke 21, whichis adapted to engage around the frame A. The yoke defines arms 22, whichare provided with aligned recesses 23 for receiving the terminals of theshaft 18.` One terminal of the shaft 18 is provided with a lock nut 24,

rWhile the other end can be provided with a "removable cotter pin or thelike 25. This means edectively holds the Ashaft 18 in position againstdisplacement. A guide way 25 the said dog 26.

engage the ratchet Wheels 17.

is secured in any preferred manner upon the body portion of the lever 20and slidably supports the dog 26 which is adapted to This dog 26 isnormally urged into engagement with the Vratchet Wheels 17 by means ofan expansion coil spring 28 which is coiled about the shank 29 of thedog and bears respectively against the outer end of the dogr and againsta guide 3() provided for the shank 29 of An operating handle 31 l ispivotally secured to the handle of the lever 20, as at 32 andthi'sihandle is connected,

bymeans of a link 33, with the shank 29 of :the dog Aing nwardly'on thehandle 31, the dog 26 26, and it can berseen that by presscan ,be slidoutwardly and away from the ratchet teeth inforder to permit the .returnmovement sition withoutmovement ofthe drum B. Ttfisfobvious, however,that when` the dog 26 r'sasv downward movement is imparted to theleofthe lever to its lowermost pothe' ratchet Wheels 17, and whenvergthei drum will be rotated. Upon up- Ward movement of the lever 20,the dog 26 will simply ratchet over the ratchet Wheels 17 andY impart nomovement to the drum B.

The means D for preventing retrograde movement of the drum B consists ofa slid ing dog 35 Which can be mounted in suitable guides 36 secured tothe standards or side pieces 11 and 12. This dog 35 is disposed belowthe ratchet Wheels 17 on opposite sides of the ratchet Wheels from thedog 26 and is normally urged into engagement With the periphery of theratchet Wheels by means of an expansion spring 37, which is coiled aboutthe shank 38 of the dog 35. This spring bears respectively against thelower end of the dog 35 and against a guide Way 39 formed for the shank38 of the said dog. If desired, a handle 40 may be formed upon the dog35 in order to permit the depressing thereof.

The lifting standard E is slidably mounted Within the frame A andincludes the side pieces 41 and 42, which are connected at their upperends by means of a head 43 and their lower ends by means of a bottomplate 44. These side pieces 41 and 42 are disposed vvithin the guideways 13 formed in the standards or side pieces 11 and 12 of the frame A.

In order to permit free sliding movement of the lifting standard E, theside pieces 41 and 42 thereof are provided with slots 45 which receivethe shaft 18. These slots 45 are in the nature of guide Ways, as theshaft 18 forms a guide pin therefor.

The head 43 may have its upper surface concaved, as at 46,. in order topermit the same to conform to the configuration of a vehicle axle or thelike. An aperture 47 is formed centrally within the head 43 and forms aguide for the pulling chain F".

The chain F is formed relatively short and is primarily intended to beused for lifting purposes, but can also be used for connesting thedevice to a support, when theV device is being used as a pullinginstrument.`

One end of the chain F can be provided With a hook 48 to permit the sameto be connected to the lower end of the lifting standard E. The otherend of the chain is placed partly about the drum with the chain links 1nthe openings 15 and in the connecting slots 16T which effectively holdsthe same in place, during operation of the drum.

Then the improved pulling and liftingl device is to be used as a jack,the hook 48 is hooked over the` bill of a hook 49,7Which is secured tothe plato 44, carried by the lower end of the lifting standard E.

In use, the device is placed under 'the vehicle in the ordinary manner,with the lift-L tobefore described, which will pull up the liftingchain, and thus lift up the lifting standard E and effectively raise thevehicle axle or other Work.

lVlien it is desired to return the lifting standard to its normallowered position, it is merely to depress the dog 35 against the tensionof the coil spring 37 and push down upon the lifting standard E.

Uien the improved liftin and pulling device is to be used for pul ingpurposes, the base plate l is anchored in any preferred manner to asupport, such as a support G as shown in Figure 8 of the drawings. Thissupport has been shown to be in the nature of a post, but it is to beunderstood that the base plate can be secured to any rigid member. Thechain F can be utilized for anchoring the device to the support, and thesame is extended about the support and through guide notches or slots lformed in the ends of the base plate 10. The upper face of the plate 10is provided with cross notches 52 in which the cross links of the chainare adapted to rest, thus connecting the chain and the device firmly tothe support. N ovv, when the device is to be used for pulling the chainF is disconnected from the hook 49 and removed from the device and usedfor holding the device in position as stated and the relatively longchain F is extended through the aperture 'i7 in the head 43 which formsa guide for the same, and one terminal of the chain is then secured inany preferred manner to the device to be pulled. The inner end of thechain is partially passed about the drum as heretobefore descrlbed. Thelever is then operated and the chain is pulled inwardly by the drum Band this effectively exerts a pulling action upon the device, to whichthe chain F is attached.

From the foregoing description, it can be seen that a simple andeflicient device has been provided for use either as a lifting jack oras a pulling tool.
